I liked the presentation on Exploring the Possibilities with Free and Open Source AI Tools. I list the sites again here, and sometimes there are some extra notes from my own trials. Development tools Link to heading Codeium, here the AI assists on the task at hand, it may even suggest an algorithm to your initial description. http://www.pitagoral.com/posts/headless_gmn/ Sun, 04 Feb 2024 00:00:00 +0000 http://www.pitagoral.com/posts/headless_gmn/ Optimize resources Link to heading If you are confortable using ssh, command line and want to have extra resources availabe for the pi, then, this section interesting. Activate ssh network connection with raspi-config, and setup key pair authentication. use nfs for accessing files in my linux environment: sudo apt install nfs-kernel-server Export /home/rms so it can be accessed via nfs in the local network: cat /etc/exports /home/rms 192.168.1.0/24(rw,sync,all_squash,no_subtree_check,anonuid=1000,anongid=1000) remove a few not required services, getting a headless system: sudo -s # session as root apt remove realvnc-vnc-server apt remove nomachine systemctl stop cups systemctl disable cups systemctl stop anydesk systemctl disable anydesk systemctl stop smbd systemctl disable smbd systemctl stop nmbd systemctl disable nmbd systemctl stop hciuart systemctl disable hciuart systemctl stop bluetooth systemctl disable bluetooth systemctl stop ModemManager systemctl disable ModemManager systemctl stop lightdm systemctl disable lightdm By using XForwarding yes in /etc/ssh/sshd_config it is possible to connect via ssh to the pi and still run applications like skyfit2: ssh -X meteorpi . http://www.pitagoral.com/posts/gmn/ Sat, 03 Feb 2024 00:00:00 +0000 http://www.pitagoral.com/posts/gmn/ The Global Meteor Network (GMN) uses cameras distributed all over the planet to measure meteor events. The project provides detailed instructions on how to setup a system being a popular option using a Raspberry Pi 4 with either an IP Camera connected to its ethernet port or a camera attached to the MIPI (Mobile Industry Processor Interface) connector. For my installation, the camera should be very discrete so no big enclosure could be used.
